辽河坳陷兴隆台油田成藏特征与成藏模式

利用地球化学、地质资料对辽河坳陷兴隆台地区的成藏特征进行了系统研究,认为研究区具有多油源供烃、多类型输导、多期次充注的特点。油源对比研究表明,油气主要来源于清水洼陷,其次为陈家洼陷,其中清水洼陷沙三段为主要烃源岩。含氮化合物指示油气沿着断层、砂体、不整合面等多种输导体,从生烃洼陷向构造高部位进行运移。流体包裹体与烃源岩生烃史显示研究区发生了多期成藏,主要成藏期为东营末期。综上,建立了以下3种成藏模式:潜山油气藏的"单源供烃、断层-不整合输导、早期成藏模式",沙三段油气藏的"自生自储、断层-浊积砂输导、早期成藏模式"和浅层沙二段、沙一段、东营组油气藏的"多源供烃、断层-砂体输导、晚期成藏模式"。     

土热传导系数及模型的研究现状和展望

近年来,随着全球能源消耗的增加,对新能源的开发和利用日益重要。地热资源作为一种清洁环保的新能源已经开始引起广泛的关注,对岩土材料的热性质研究也逐渐受到国内外学者的重视。土的热性质包括热传导系数、热扩散系数和比热容。其中,热传导系数作为其中最重要的性质,它不仅决定了热量在土体中的传播速度和土体温度场的分布,同时也是各种地热泵、能量桩等建筑热工结构设计中需要考虑的主要参数之一。首先介绍了土热传导系数的工程背景和研究意义,描述了土中的热量传播方式和类型,阐述了热传导系数的概念,并分析了土热传导系数的各种影响因素（含水率、密度、矿物成分、温度等）。在此基础上,总结了目前国内外土热传导系数模型的研究现状,并对各个模型的优缺点进行了简要的分析和评价。最后,提出了对土传导系数及模型研究的建议和展望。     

清水沟北汊流路入海泥沙对东营港影响的数值分析

本文用平面二维潮流泥沙数学模型,模拟了清水沟流路北汊入海口海域的潮流泥沙扩散和河口淤积延伸方向等问题。在此基础上从流速场分布,泥沙扩散浓度分布及淤积厚度零米线的范围及河口淤积延伸方向等方面探讨了入海泥沙对东营港的影响。结论认为如果按此口门入海,入海泥沙不会对黄河海港产生直接淤积影响。     

陕西省镇安县金龙山金矿带控矿因素与找矿方向分析

[摘要]金龙山金矿床主要赋矿地层为中泥盆统杨岭沟组的中厚层灰岩,上泥盆统南羊山组的粉砂质(钙质)页岩夹中薄层灰岩,下石炭统袁家沟组的薄-中厚层灰岩、粉砂质灰岩。已知矿化体见于多个层位的多种岩性岩石中。有利岩性对金矿化具有控制作用。金龙山矿区存在着明显的褶皱剪切带,控制了以金、汞锑成矿带。由于受南北向构造的影响,本区存在着“东西成行,南北成列冶区域矿产的分布特点。北东、北西断裂在有利岩性部位交汇形成的“米冶、“V冶,正是由于多组断裂的交汇形成了成矿热液的通道,当这些透入性破裂构造发育在有利含矿岩层的剪切带上时,破碎岩石可直接构成工业矿体。我们得出的金龙山金矿成矿热液来源于深部、向上运移中不断演化的混合热液,在有利的岩性与构造成矿观点,在南秦岭沉积岩区金矿勘查领域可扩展许多地区,浸染状矿化有可能发现于除南羊山组之外的四峡口、杨岭沟、冷水河、西口组,镇板断裂北侧的九里坪组、铁厂铺组等钙泥质粉砂岩层中;脉型矿化可能发育于除袁家沟组、冷水河组之外的二叠系、三叠系的界河组、九里坪群灰岩中。     

区域煤炭资源流动及其宏观经济效应初探——以内蒙古为例

从流量、流向以及流动通道三方面,探讨了内蒙古煤炭资源流动平衡现状,采用向量自回归模型解析了内蒙古煤炭资源流动与其宏观经济发展的相互作用关系,结果表明:(1)内蒙古已成长为中国最大的能源输出基地,煤炭交流活动主要集中在其周边地区,尤以华北和东北地区为主。(2)内蒙古铁路煤炭运能不足,缺乏独立、完善的运输网络。(3)内蒙古煤炭资源流动与区内经济发展水平的提高、重工业的发展、第三产业发展以及税收增长均存在着长期稳定的均衡关系,且对区内重工业发展和税收增长具有明显的单向推动作用,但对区内人均GDP和第三产业发展的促进作用相对比较微弱。(4)建立独立、完善的煤炭运输网络;重视发展煤炭运输及其相关服务业;转变能源输出战略,提高输出资源附加值,带动区内煤炭工业以及整体经济发展水平提高的政策建议。     

Notions of justice held by stakeholders of the Newfoundland fishery

Justice is an important and contested issue in the governance of fish stocks threatened by overexploitation. This study identifies the notions of justice held by stakeholders of the fishery in Newfoundland, Canada, using qualitative interviews, and interprets these notions in light of established justice theories. The interviews are analysed using inductive and deductive coding. A central result is that inshore fishers are seen as the main claim holders, with a claim to participate and be listened to, and the opportunity to make a living from the fishery. Moreover, rules play an important role in the justice notions of the interview partners, and their justice notions are clearly plural. The stakeholder notions of justice in the Newfoundland fishery resonate with the emphasis on recognition, participation and distribution as important aspects of justice within the environmental justice approach [59-61] (Schlosberg 2004, 2007, 2013).     

Culture,demography and biogeography of sponge science: From past conferences to strategic research?

Perceived changes in the culture of sponge science and sponge conferences served as motivation for an evaluation of the sponge science community and research, over time and at present. Observed changes included a decrease in proceedings publications on sponge fossils and freshwater sponges, sponges from temperate environments, review papers and data syntheses, frequency of aquarium studies, and number of species investigated per publication. Publications on recent sponges, hexactinellids, calcareans, marine, Indo‐Pacific and warm‐water sponges increased, as well as the number of authors per publication and the proportion of field studies. Studies at the level of specimens and ultrastructure were gradually replaced by molecular approaches, but studies at the community level remained stable. The five sub‐disciplines morphology/taxonomy, phylogeny/evolution, physiology, ecology and faunistics also retained about equal proportions over time. Conference publications related to taxonomy, phylogeny and biodiversity prevailed, whereas those on management and conservation were rare, possibly because studies on sponge recovery, survival and mortality were also scarce. The community of sponge scientists has grown and become more diverse over time, presently representing 72 nations. The gender distribution evened out since the first sponge conference and presently favours women at early and men at late career stages. Although stated research interests are generally dominated by physiology and ecology, taxonomy and evolution are favoured after retirement. Sponge science has become more dynamic, but maybe also more competitive and less inclusive. We now face the dual challenge of safeguarding against the loss of some sub‐disciplines, and fostering the collaborative, helpful culture characteristic of sponge science.     

The anisotropy of loess magnetic susceptibility in the northeastern fringe of Qinghai-Xizang Plateau as an indicator of palaeowind direction

Estimates of the palaeo-subaerial wind direction were studied systematically for the first time by using the anisotropy of loess magnetic susceptibility (AMS) measurements in the northwestern China. One hundred and forty undisturbed oriented aeolian loess samples were collected from Lanzhou, Linxia and Wudu areas for AMS measurements, which indicated the subaerial wind directions were not the same while the loess deposited. From the Early Pleistocene to Middle Pleistocene till Late Pleistocene, the wind direction experienced an anticlockwise rotation in the studied area. We suggested this change was related to the uplift of the Qinghai-Xizang Plateau and the adjustment of current and landform effects.
